More than three years after the pandemic slammed movie theaters, reducing the flow of new films and keeping patrons away, operators hope a slew of wide releases this summer will finally get those who have grown accustomed to streaming movies at home back into theaters, the New York Times reported. If they do return — for “The Little Mermaid,” “Barbie” or the latest from the Spider-Man and Indiana Jones franchises — moviegoers may find that the spaces look and feel different. Cinemas were already upgrading before the pandemic — bringing in cushier seating, bigger screens, better sound equipment, and tastier food and beverage options. But many theaters also went into 2020 with thin margins and may have survived only because of federal pandemic relief programs. Now cinemas are spending millions of dollars to beef up their offerings and surpass moviegoing of old.
